Some time ago I installed a blueprint 430hp 383 longblock crate engine in my camaro and have since done nothing but fight with issues of fuel in my oil with it. Now the blueprint website recommends using a 750 carb with it but my mechanic said that was too big and that's why I'm dealing with the fuel in my oil issue. When talking to the blueprint customer service rep he said the same thing, but I'm not sure if that's the case since that's what the website specs on the motor recommend or if they are just trying to screw me on my warranty. Should I have gone with a 600-650? Or should the 750 Holley I put on it have worked?
